Generate AI Marketing Reports from Google Sheets with GPT-4 & PDF.co

This n8n workflow automates the generation of marketing performance reports by extracting data from Google Sheets, where it aggregates spend by marketing channels like social media, search, and email. It then leverages GPT-4 via OpenAI to produce insightful summaries highlighting key trends, ROI highlights, and recommendations, transforming raw data into actionable intelligence.

Next, a code node formats the aggregated data and AI summary into a Mustache-compatible structure for a custom HTML template. The workflow integrates with PDF.co to render this into a polished, branded PDF report, ready for sharing with stakeholders.

Benefits include significant time savings on manual reporting, consistent professional outputs, and AI-driven insights that go beyond basic spreadsheets. Ideal use cases: daily/weekly marketing dashboards for agencies, e-commerce teams tracking ad spend, or sales funnels monitoring performance across channels. Easy to customize for email delivery or additional filters.
